#DM463 Diff Mount Bushings for E46 M Gallery

Using a rubber mallet or C-clamp, tap in front bushing as indicated by arrow.

Install aluminum center pin from opposite side, as indicated by arrow, using a press or C-clamp.

Press bushings into rear diff cover as shown.
NOTE: Extreme care must be taken when removing old bushings from the diff cover. If cover is cracked during removal, do not re-use the cover. See following pictures for what can result from a cracked cover.

The bushing in this photo and the next was installed in a cracked diff cover. A cracked cover subjects the bushing to the weight and torque of the diff. The bushing may be strong enough to support the diff's weight, but it cannot survive the torque that it is subjected to when there is a crack in the cover.
In both these photos, you can see the indentation where the bushing was stressed by the lack of support, and where it eventually separated due to that stress.
